Classification of Planar Curve Using the Zero-Crossings Representation of Wavelet Transform

摘要

A method of planar curve classification, which is invariant to rotation, scaling and translation using the zero-crossings representation of wavelet transform was introduced. The description of the object is represented by taking a ratio between its two adjacent boundary points so it is invariant to object rotation, translation and size. Transforming this signal to zero-crossings representation using wavelet transform, the minimum distance between the object and model while shifting the signals each other, can be used as classification parameter.
